Calpol

2 oz vodka
12 oz bottle Smirnoff Ice
2 oz Red Bull energy drink

Invented at Kent University in 2005. Named Calpol because thats what the contributor thought it tasted like. Very easy to drink, but with about 4 units it's strong stuff.Pour Smirnoff Ice into a pint glass. Add the vodka. Fill up with Red Bull, and serve.
